Answer 2

The moles of sulfuric acid that will contain 64 grams of sulfur are 2 moles

Explanation:

We are given:

Mass of sulfur atom = 64 grams

We know that:

Molar mass of sulfur = 32 g/mol

The given chemical formula if $H_2SO_4$

1 mole of a compound contains 2 moles of hydrogen atom, 1 mole of sulfur atom and 4 moles of oxygen atom

Molar mass is defined as the mass of 1 mole of a substance

Applying unitary method:

32 grams of sulfur is present in 1 mole of sulfuric acid

So, 64 grams of sulfur will be present in = $\frac{1}{32}\times 64=2mol$ of sulfuric acid
